viiELL-DRILUNG. CABLE.

T will whom, 1' t DML!! cone/:rn:

Be it known that I, J osEriI REID, a citizen of the United States,'and a resident of Oil City, in the county of Venango, State of' Pennsylvania, have invented certain new and useful Improvements in Well-Drilling (lables,

of which the following is a specification.

It is generally well knpwn that for successfully drilling ldeep wells the elasticity oi" the drilling-ropel plays an important part in the stroke of the tool. ropes, however,

.llemp which have the quality of e asticity, are undesirable for deep well-drilling for well-known reasons. It has been attempted to combine the hemp rope with a steel cable by splicing the steel cable to the hemp rope-that is 'to say, by weaving the strands of'th'e steel cable over and under the strands of the hemp rope. This method is objectionable, because the joint is notdurable, it being found that the i hemp ro e and relay the strands of the hemp rope tig itly and closely about the steel rope as a core or center, suitably secure the ends o the strands of the hem rope, and clamp the splice or joint thus pro 4uced at suitable intervals by semicylindrical clamps held together by rivets passing through both the hemp and steel ropes without cutting orv breaking the fiber or strands in either. The end of the steel rope is preferably. tapered before being introduced into the hem rope by removing a suitable number of t e individual wires from its several strands, and the tapered end is wire Wound or bound to prevent unraveling. The end ispreferably provided with a further Winding or binding below each rivet to prevent uiilaying or unraveling of the strands of the wire rope under the pull of the A through-rivet.

My invention Will be fully understood upon reference to the accompanying drawings, in which- Figure 1 is a view of the joint produced by my invention. Fig. 2 isa view of the two Specification of Letters Patent. 'Application filed March 7, i905. Serial No. 248,812.

ropes presented. coaxially. Fig. 3 is a tripsig.

4 is a longitudinal section through the end of the joint and its finishing-clamp.

A represents the joint to be forined,which consists of the central steel or wire ro e core l, thesurrouiiding hemp rope 2 lai about the core, the clamps 3, 4, and 5 for securing the hemp rope to the steel core and preventing'relative longitudinal movement between the parts.v

In producing my improved well-drilling cable I take a suitable length of hemp rope, preferably haWser-laid, and unravel theends, as shown at 2a in Fig. 2. I then take a length of steel or Wire cable which, with the length of Manila rope, will be suiicient for. the drilling operations to be undertaken, and I ta er the `end of the steel rope, as shown at 1a, y cutting back one or more of the wires on each strand, after which the tapered end is bound, as shown at 6, by means of a wire or by brazing or soldering. I also bind it, as shown at 7, at a point adjacent to the location of each rivet to be referred to.

In producing the improved splice the tapered eno 1a of the Wire rope is drawn into the end of the rope 2 by the wires 10, the strands 2l are twisted at the proper pitch to correspond to the angle of lay to be imparted to the strands, and said strands are laid about the steel-rope center. When a sufficient length of lay has been made, the joint is finished by applying the clamps 3, 4, and 5, which are secured by rivets passing through both the Wire and manila ropes immediately above the windings 7 thereon, While clamp 5, being eX- teriorly threaded, receives a ta ered sleeve 23, which has been passed over t e end ofthe wire rope previous to the commencement of the operation of forming the splice. By means of this clamp 5 and threaded taper sleeve 23 the ends of the laid strands may be permanently secured and the desired taper inish be provided at the end of the splice.

A s lice or joint produced as herein describe will be as strong as the weaker ofthe two ropes. It will work satisfactorily over pulleys or guide-slieaves without producing undue wear on the parts, and there will be no cutting or undue wear upon the strands of the rope at the-splice or elsewhere.

v The term's laid or laying are used in this specification in their technical sense as understood by ropemakers--that is to say, to convey the idea of laying the'strands of a IIO rope b twisting and spirally winding' them. Thus t e term laid joint conveys the idea of a joint formed byusing one of the rope ends as la core and taking the unlaid strands of the other rogo and twisting and Winding them about sai core or windin them while maintaining the twist that the have already received in the manufacture o1Y the rope.' y

Having thus described my invention, the following is what I claim as new therein 'and desire to secure by Letters Patent:

1; A composite Well-drilling cable, having` its sections united by alaid `oint.

2. A composite Well-drillmg cable having.

' rope around the wire rope andsecuringV them n' by clamps.

5. A composite ro e having the end of its steel rope wound or ound, and the strands of its hemp rope laid about said steel rope by twisting and Winding, and secured thereon by a c amping-rivet passing diametrically through both ropes just above the binding on the steel rope.

6. A composite rope havin the end of its wire section tapered and boun at the tapered end and above the same, and having the end of its hem section unlaid, and thestrands thereof tig tly twisted and closely wound u on the steel section and secured thereto by c amps and diametric through-rivets.
